[Development] FYI: MSVC 2005, 2008 and 2010 dropped in Qt 5.7

[Thiago Macieira]

https://codereview.qt-project.org/121146 integrated, so configure.exe will now 
refuse to compile with MSVC older than 2012, as discussed in the C++11 & LTS 
thread in June.

The mkspec files remain if someone wants to compile non-Qt code using qmake.

I've just uninstalled MSVC 2010 from my Windows machine, which was low on disk 
space.
